The process of turning a colored image into black and white is known as gray scaling. A colorful image can be converted to monochrome in python using more than one method. In this article, we will look at one of
Original image:Converyted grayscale image:Convert an Image to Grayscale in Python Using the color.rgb2gray() Method of the scikit-image ModuleThe color.rgb2gray() takes an image in RGB format as input and returns a grayscale copy of the input image. The below code example demonstrates how ...

Converting an RGB image to grayscale manually involves calculating the intensity of each pixel using a weighted formula. The most common formula is: Gray = 0.2989 * R + 0.5870 * G + 0.1140 * B This formula accounts for human perception, where the green channel has the most significant impac...
